There is much to admire in Kirsten A. Seaver's scholarly examination of the Vinland Map. However, my own researches in recent years have brought new facts to light which exclude Fr Josef Fischer as the forger.

When "Maps, Myths and Men" was written, nobody knew where the medieval manuscripts bound with the map were located prior to 1957.Today, we have documentary evidence to show that they came from Zaragoza Cathedral Library (and not, as Kirsten Seaver speculated, a library in Moravia with links to her main suspect). It is highly significant that Enzo Ferrajoli, the book dealer who "discovered" the map in the late 1950s, was subsequently convicted of stealing books and manuscripts from Zaragoza Cathedral Library.

More astonishingly, experts spent decades debating the Vinland Map's authenticity without anybody realising that the supposedly "15th-century" map incorporates identifiable errors copied from an 18th-century engraving! Had this simple fact been noticed at the outset, the whole needless controversy could have been avoided. Kirsten Seaver is no more to blame for overlooking this damning piece of evidence than any of the other experts who missed it. It does mean, however, that her 2004 book is incomplete.

For anyone with an interest, full details of these recent discoveries (and an in-depth investigation of the Zaragoza Cathedral thefts) can be found in my (self-published) 2018 book: "A Sorry Saga: Theft, Forgery, Scholarship... and the Vinland Map," by John Paul Floyd (ISBN: 978-1719979788).
